To all whom'-may concern:

Be it known that l, DONALD S. Bannows,

a citizen of the United States, residing at Rochester, in the county of4Monroe and State of New York, have invented certain new and usefulimprovements in Car Underframes; and l do hereby declare the followingto be a full, clear, and exact description of the invention, such aswill enable others skilled in the art to which it appertains to make anduse the same. My invention relates to car underframes for railway carsand more particularly to a strong, reliable and efficient metallicstructure adapted to be applied generally to wooden underframe cars toreinforce the underframe thereof so as to adapt said cars for use undermodern service conditions.

'lo this end one of the principal features of the invention, generallystated, is to provide a metallic structure adapted to be used with theunderframe of wooden cars, said structure being used to reinforce thecar sills and designed to receive the butling and pulling shocks whichare transmitted thereto by the draft rigging.

Particularly stated, the invention consists in providing a carunderframe including in combination a backstop member associated with amovable element of the draft` rig ing and connected to a plurality ofmem ers forming the draft sills, the bolster to which said draft sillsare connected, and diaphragm means suitably connected by gusset platesto the bolster in the rear thereof for reinforcing the strength value ofthe severall parts comprising the car underframing.

Another object of the invention is to provide a car underfrarne andreinforcing' means therefor involving diaphragm members of simpleconstruction at the rear of the bolster, said members being increasedfrom a relatively shallow depth or cross sectional area from a pointadjacent the reinforcing center sill members to a relatively large crosssectional area or depth substantially equal to the height of the bolsterand immediately adjacent the rear thereof.

A' further object of the present invention is to provide a car'underframe including a plurality of gusset plates, some of said platesbeing arranged to effectively connect the draft members to the bolsterforwardly thereof, said gusset plates being arranged adjacent ithebackstop casting, and other of said gusset plates serving to unite thereinforcing diaphragm means and bolster at the rear thereof, theuppermost of said last named gusset plates bridging and connecting thediaphragm means and overlying the bolster.

A still further object of the invention resides in the combination withcenter sill remforcing members, a top gusset plate bridging andconnecting ,said members at the rear of the bolster, diaphra reinforcingmeans formed with an o set portion adapted to receive andfit said gussetplate and having a shoulder portion at the rear thereof connected to thecenter sill reinforcmg members, and bottom gusset plates underlying saiddia hragm means and shoulder portion, said ttom gusset plates beingconnected to the bolster, diaphragm means and center sill reinforcingmembers.

'lhere are other features of the invention as will be pointed outhereinafter in connecnection with the detailed description of myinvention illustrated in the accompanying drawings in which Flgure l isa plan view of my improved construction.

Figure 2 is a central vertical longitudinal sectional view through theconstruction shown in Figure l. v

Figure 3 is a horizontal sectional view with parts shown in section andbroken way, and other parts illustrated in elevaion.

Figure el is a transverse vertical sectional view on the line M ofFigure 3.

Figure 5 is a transverse vertical sectional view on the line 5-5 of Fire 3.

ln the drawings ll have illustrated only a portion of the car underframeadjacent the body portion. lt is to be understood, however, that thestructure is duplicated at the opposite end of the car and that thecenter sills hereinafter referred to are preferably continuous, the saidsills being adapted to extend from end to end of the car. rlfhe carunderframe preferably includes the usual end sill and associated parts,not shown, but as is well understood by those skilled in the art.

Referring to the drawings in which corresponding reference charactersdesignate similar parts in the several views, the center sills of thecar are provided with center sill reinforcing means, said reinforcingmeans titi lilla sills of the car underframe.

plate 4, shown in the form of a stiffening channel, the flangesthereof'being connected to the inner opposed faces of the reinforcingsills 1 by means of rivets 5. Filler strips or inserts may be utilized,if found necessary, to accommodate the parts to A. R. A. standardmeasurements, as will be understood.

The draft members or sills are each preferably formed of angle members 6and 7, the respective vertical flanges thereof being overlapped andunited by means of a plurality of'rivets 8 extending throughout thelength of said members. The horizontal flange 9 of the upper anglemember 6 is relatively wide and is preferably connected, by means of adouble row of rivets 10, to the horizontal flange of the angle or centersill reinforcing member, the respective vertical flanges of said anglemember 6 being spaced further apart than the vertical fla es of thereinforcing sills to provide for t e use of modern draft rigging and itsassociated parts. The horizontal flange 11 of the lower angle member 7extends outwardly ofthe draft sills and has connected thereto, by

means of rivets 12, the forwardly extending portion of the bottom gussetplate 13, the rear portion of said gusset plate being connected by meansof rivets 14 to the bottom flange of the bolster. The horizontal flanges11 of the angle members 7 are preferably tied together by means of thecro bar eX- tending transversely of the draft sills intermediate theends of the backstop member,

- said cross bar being connected to the horizontal flanges 11 by some ofthe rivets 12, as shown.

The inner ends ofthe built-up draft sills are connected by means ofangle members 15 to the bolster, the ends of said draft sills preferablyterminating short of the vertical web portion of the bolster, as shown.Rivets 16 unite one arm of the angle member to the'adjacent draft sill,the other arm of said angle member being connected to the bolster web bymeans of rivets 17. The connecting angle members are preferably arrangedupon the outside of the draft sills, as shown.

Interposed between and connecting the inner ends of the draft sills is abackstop member 18, said member being preferably spaced from the bolsterand adapted to receive buffing shocks from a movable element of thedraft rigging. shown herein as the yoke 1 9 of the well known-Farlowequipment. A follower member of the draft rigin is indicated by thenumeral 20. The

ac stop casting or member 18 is 'formed with a front wall portion 21having a buffing face adapted to receive the bufling shocks through thestood. Side walls 22 of the backstop casting are formed integral withthe front wall and are designed to be connected to the inner opposedfaces of the draft sills and more particularly the overlapped verticalflanges of the respective angle members 6 and 7. Certain of the rivets 8serve to connect the backstop to the draft sills. The rear wall 23 ofthe casting is united to the front wall by means of vertically andhorizontally arranged webs or flanges 24. The horizontal flange or webalso unites the side walls of the ackstop. The rivets connecting the'side walls of the backstop castin to the draft sillsextend-througl1o'ut the le side walls and serve to firmly unite thebackstop member to the'associated angles 6 and 7, certain of said rivetspassing through both vertical flanges of the angle members' and other ofsaid rivets passing through but the vertical flange of the upper anglemember 6.

' The means reinforcing and bracing the forward portion of theunderframe above described, includes spaced vertical diayoke member, aswill be underngth of said l phragm members 25, each associated with anadjacent center sill reinforcing member and longitudinally disposed withrelation there to. Each diaphragm member is preferably formed of a Z-barhaving at its forward end an outwardly rejecting flange 26 adapted to beconnected) to the rear face of the web of the bolster by means of therivets 17 hereinbefore referred to as connecting one arm of the anglemember 15 to said web. The

vertical web portion of each diaphragm member increases in depth from 'apoint at the rear of the bolster .adjacent the center sill reinforcingmembers tothe rear edges of the bolster flanges, said web portionlextending between the flanges and terminating in the outwardlyextendingflange 26, as shown. Each diaphragm member is rovided with anupper flan e 27 connected to the horizontal flange of t e center sillreinv forcing members by means of rivets 28, said flange being arrangedto extend inwardly and having its forward o rtion offset to underlie thetop flange o the bolster, as

. clearly shown in Figure 2. The rear end of the flange 27 is relativelythickened to form a shoulder recessed portion 29 adapted toref ceive thetop gusset plate 30.

The top gusset plate 30 is interposed between the lower flanges of thecenter sillreinforcing members and the flanges 27 of the ing saidmembers and extending outward diaphragm member, said gusset plate bridgylll Aso

= ed to extend annee therefrom suitable distanc u on each side of thecenter sills, as shown. e forward portion of the gusset late 30 isadapted to overlie the bolster an is connected to the top flange thereofby means of a plurality of rivets 31 arranged upon the respective sidesof the webportion of said bolster. The rear portion of the gusset plateterminates adjacent the shoulder portion 29. lt will be obvious that theinterpositioning of the single usset plate 30 between the upper anges oft e diaphra members and the center sill reinforcing sills serves toprovide a connection of relatively light weight and maximum strengthvalue.

'llhe dia liragm members are each rovided wit lower outwardly exten ingflanges 32, said dangesbeing connected to the `respective gusset plates33 by means of rivets 3d. 'lhe flanges 32 conform to the incline ortaper of the web portion of the diaphragm members and extend throughoutthe bottom ed e thereof. Each gusset plate 33 is provide with aninwardly extending portion 35, said inwardly extending portion extendingthrouhout the length thereof. The forward en of each gusset plate 33 isconnected by means of rivets 36 to the lower flange of the bolster, saidgusset plate being interposed between the bottom Harige 32 an theuppermost face of the lower bolster flange 3. The rear portion of eachgusset plate 33 underlies the shoulder portion 29 of the upper diaphragmdan e 27 and is adapteyond sai shoulder portion and be connected to theunderface of the center sill reinforcing members by means of rivets d?.

The diaphragm members are preferably positioned out of lon itudinalalinement with respect to the dra sills, the inwardly extending danges27 of the diaphragm members bein preferably in longitudinal alinementwit the outwardly projecting horizontal anges of the members 6 and 'l'forming the draft sills.

An underframe for railway cars constructed in accordance with my'present invention provides a relatively light weight structureintimately associated with the bolster and capable of being readily andinexpensively assembled. llt will also be obvious that the backstopmember is edectively reinforced so as to receive the bung loads, thereinforcing means being ada ted to transmit to the car sills the bun'oads at points where the latter are best ab e to withstand theexcessive strains.

ln addition it will be seen that an underframe is conveniently providedfor older types of cars wherein modern draft rigging equipment can beeasily installed.
